Biochem/physiol Actions

Pep2-8 is a potent PCSK9 (proprotein convertase subtilisin/kexin type 9) inhibitor that selectively binds to PCSK9 and interferes with LDL receptor binding to PCSK9. Pep2-8 restores LDL receptor function and LDL uptake of PCSK9-treated HepG2 cells.
Pep2-8, a good mimic of epidermal growth factor precursor homology domain A (EGF-A), serves as a competitive inhibitor of low-density lipoprotein (LDL) receptor binding. It can be used as an anchor peptide in phage-display experiments to bind an extension peptide library to the groove site.

PCSK9 (proprotein convertase subtilisin/kexin type 9) is a negative regulator of the hepatic LDL receptor, and clinical studies with PCSK9-inhibiting antibodies have demonstrated strong LDL-c-lowering effects. Here we screened phage-displayed peptide libraries and identified the 13-amino acid linear peptide Pep2-8

Proprotein convertase subtilisin/kexin type 9 (PCSK9) regulates plasma LDL cholesterol (LDL-c) levels by promoting the degradation of liver LDL receptors (LDLRs). Antibodies that inhibit PCSK9 binding to the EGF(A) domain of the LDLR are effective in lowering LDL-c. However, the
